What are the PIF ATP Rankings?
The PIF ATP Rankings is the ATP's historical objective merit-based method used for determining entry and seeding in all tournaments for both singles and doubles, except as modified for the Nitto ATP Finals.

They are known colloquially by fans as 'the world rankings'. For example, when Novak Djokovic is No. 1 in the PIF ATP Rankings, he is said to be the No. 1 player in the world. Or a player who is No. 7 in the PIF ATP Rankings is said to be a 'Top 10 player'.

What is the ranking structure and formula?
The breakdown - for singles and doubles – includes 18 events for all players. *In singles, the Nitto ATP Finals is an extra event (19th) in the ranking breakdown. Top players who compete at all automatic-entry events will have the following breakdown:

• One (1) Nitto ATP Finals* (additional event in the ranking breakdown)
• Four (4) Grand Slams
• Eight (8) automatic-entry Masters 1000s
• Six (6) ‘Best Other’ (United Cup, ATP Masters 1000 Monte Carlo, ATP 500, ATP 250, Challenger, ITF).

What is the PIF ATP Race To Turin?
The top seven players in the PIF ATP Race To Turin after the ATP Masters 1000 event in Paris qualify for the Nitto ATP Finals. If there is one current-year Grand Slam champion positioned between eighth and 20th in the Race, he qualifies in eighth place. If there are two current-year Grand Slam champions positioned between eighth and 20th in the Race, the highest-placed of those players becomes the eighth and final qualifier; the lower-placed Grand Slam champion will serve as the alternate. If there are no current-year Grand Slam champions positioned between eighth and 20th, then the player at eighth in the Race will claim the eighth and final berth.

How does the PIF ATP Doubles Rankings work?
The PIF ATP Doubles Rankings is based on calculating, for each player, his total points from his best 18 results from all eligible tournaments, including the Nitto ATP Finals (Doubles) played in the Ranking period. For entry purposes there are no automatic-entry events, however, once a player is included in the main draw of any of the four (4) Grand Slams or the eight (8) ATP Tour Masters 1000, as a direct acceptance, a qualifier, alternate or a lucky loser or having accepted a wild card, his result in one of these twelve (12) tournaments, shall count for his ranking, whether or not he participates. The exception to this is once per player per calendar year, a player whose team is forced to withdraw after the draw has been made but prior to the team’s first match shall not have the withdrawal count as a tournament played for purposes of ranking.

What is the PIF ATP Doubles Teams Rankings?
The top seven teams in the PIF ATP Doubles Team Rankings after the ATP Masters 1000 event in Paris qualify for the Nitto ATP Finals. If there is one current-year Grand Slam champion positioned between No. 8 and No. 20 in the Team Rankings, that team qualifies in eighth place. If there is no current-year Grand Slam champion positioned between No. 8 and No. 20, then the team at No. 8 in the Team Rankings will claim the eighth and final berth.

Teams count up to 18 of their best results in a year. Each team is ranked according to its total points from its best 18 results from all eligible tournaments (Grand Slam, ATP Tour, including the Nitto ATP Finals, ATP Challenger Tour, ITF Men’s WTT) played in the calendar year.

How are players separated when they have the same amount of points?

Ties. When two or more players have the same total number of points, ties shall be broken as follows:

1. The most total points combined from the Grand Slams, ATP Masters 1000 automatic-entry tournaments and Nitto ATP Finals main draws, and if still tied, then,
2. The fewest events played, counting all missed Grand Slams, ATP Masters 1000 tournaments and Nitto ATP Finals they could have played - as if played, and if still tied, then,
3. The highest number of points from one single tournament, then, if needed, the second highest, and so on.

What is a protected ranking and who is eligible?
A player may petition the ATP CEO or his designee for an Entry Protection when he is physically injured or has a documented medical illness, serves a compulsory military service and does not compete in any tennis event, including Special Events – Exhibitions, for a minimum period of six months. The written petition must be received within six months of his last tournament.

The Entry Protection shall be a position in the PIF ATP Rankings, as determined by the player's average PIF ATP Rankings position during the first three months after his last event played. The Entry Protection shall be for entry into the main draw or qualifying competition or for special exempt consideration. The Entry Protection shall not be used for seeding purposes, Lucky Loser consideration or for entry into the Nitto ATP Finals.

The Entry Protection shall be in effect for either the first nine tournaments that the player competes in using the Entry Protection (excluding wild cards and entries as a Direct Acceptance with his current position in the PIF ATP Rankings) or for the period up to nine months beginning with the first tennis event that the player competes in, including Special Events – Exhibitions, whichever occurs first.

If a player is physically injured and does not compete in any tennis event for a period of twelve (12) months or longer, the entry protection shall be in effect for the first twelve (12) singles tournaments and the first twelve (12) doubles tournaments that the player competes in using the entry protection (excluding wild cards and entries as a direct acceptance with his current position in the PIF ATP Rankings) or for the period up to twelve (12) months beginning with the first tennis event, including Special Events – Exhibitions, that the player competes in, whichever occurs first.
